FURNITURE SPRING.

Application field July le, 1925.

To all 'whom it may 00 morn,

Be it 'known that l, VINCI-insee Blass-wsse, a citizen ot' the United States et America, and a resident of the city o't New York. borough of lvlanhattan. in thecounty and Statefof New York, have invented a new and Improved Furniture Spring'. ot which the following is a full, clear, and exact. description.

This invention relates to furniture springs and pertains more particularly to an improvement in springs ior beds, couches, or the like7 and of the type which includes a plurality of volute spring` elements, the upper and largerend convolutions of which are connected and braced by suitable coil spi-ing' connecting` elements. v

Heretoi'ore these connectingelements, which are preferably in the nature ot' crossed coiled contractile springs, are connected to the larger end convolutions of the voluto springs insuch a manner as to allow, for

Arelative oircumiierei'itial shifting oi' the former with respectfto the latter, which resuits in o clashing noise, in addition to the iiailnre of the spring structure to prop'- erly support the weight of the user. To overcome this, radial otl'set portions have been provided in the lei-ger end convolutions of the volute spring within which the terminals of the cross contractile springs .are engaged.

The present. invention comprehends the provision of' n'leans for 'locking' the looped terminals ol' the cross springs within the radial offset portions, which means cons` sists et' an arcuate link, the big'ht-slmped ends of which link engageA the periphery or' the volute spring` convolution opposite to the concave side ofthe offset loops with the connecting' or side arms of the link ein bracing the portion of the looped terminals of the springswhieh lie within the ott'set loops. y

The invention furthermore aims as its principal object to provide a retainingmeans for holding the looped terminals of the springs Within the ofset terminals of the end convolution of the volute spring, which means is extremely simple in its construction, inexpensive to manufacture and apply, and which is highly eliicient in its purpose.

"With the above,y rjeeited and other objects in view, reference isjhad to the following specification and drawings in which there Serial No. l3,5762

is exhibited one example or embodiment of the invention which is in no way intended as a limitation upon the scope of the appended claims as it is to bel clearly iunderstood that variations and modifications.

which properly tall within the scope lof said claims may be resorted to when :found expedient.

ln the drawings- Figure 1 connection between the cross or connecting springs and the volute spring, which con- -nectionis constructed in accordance with the invention.;

Fig. 2 is @fragmentary perspective View of the connection and retaining means; Fig. 3 is a fragmentary sectional view thereof.

Referring,- to the drawings by characters of reference, lddesignates generally a volute spring' and 11 the upper largest vend c011- volution which is Aformed with the radial' minals 14 wit-hint the olFset loops 12 so that relatively circuni'lerential n'iovenient of the terminals 14 with respect to the convolntion 1,51 is positively precluded. r-lhe'reta-iningelement or device 15 consists of an arcuate-shaped link which comprises arcuate is aplan view illustrating'the` volute springs to `function in' side arms 1o joined by integral bightshaped i ends 17. The ends l? embrece 'the periphery of the convolution :11 on the opposite side lof which the concave portion oi the odset loops 12 is gdisposed, while the arcuate arms 16 em brace the portions of the loops or terminals 14 which are arranged within the concave side of vthe foffset loops 12. The links or elements 15 may be split links, the terminals ot which are joined together by welding or in other suitable manner. After the initial engagement of the terminals or loops 14 of the springs 13 in the oii'se-t the said links may he mede solid initially,

loops 12,.

and the terminals 14 engaged after the placement of the links or devices 15 with the terminals 18 of the loops 14 opened and Subsequently bent in place, as illustrated in Fig. 2.

From the, foregoing it will thus be seen that a retaining means for holding the terminal loopsof the springs 13 Within the oil'- setlooped portions 12, has been devised, which eectually prevents displacement and relative circumferential movement of the spring terminals 13 with respect to the convolutionsll of the volute springs 10, which retaining means is in the form of links or other devices which are extremely simple and inexpensive both in structure and mode of connection.

What is claimed is:

1.. Inra volute furniture spring having a plurality of radial Oiset receiving loops for thelooped terminals of connecting coiled contractile springs, retaining means for holding said looped terminals in the offset loops, comprising an arcuate link.

2. In av volute furniture spring lfaving a plurality of radial ofiset receiving loops for the tlooped terminals of connecting coiled contractile springs, retaining means for holding said looped terminals inthe o'set loops,.comprising an arcuate link, said arcuate link including arcuate side arms and connecting bights at the ends of the arms` 3. In a volute furniture spring having a plurality of radial otisctreceiving loops for the'looped terminals of connecting coiled contractile springs, retaining means for holding said looped terminals in the oilset loops, comprising an arcuate link. said arcuate link includingr arcuate sife arms and connecting bights at the ends of the arms, said arcuate side arms engaging around the ends of theterniinal loops and the connecting biglits engaging the opposite peripheiv of the end convolution oi" the volute spring at the juncture of the radial offset receiving loops thereof.

4.. In a volute vfurniture spring having a plurality ot' radial oii'set receiving loops Jfor the looped terminals ot connecting coiled contractile springs. retaining means for holding said looped terminals in the oii'set loops`v comprising an arcuate link-said arcuate link including arcuate side arms and connecting tights at the ends ot the arms, said arcuate side larms engaging around the ends of the terminal loops and the connecting biglits engaging the opposite peripliervv of the end convolution ol the volute spring at the juncture oi the radial oiiset receiving loops tliereoi, whereby the said terminals are permitted Jfree vertical a nd lateral roeking movement in the oii'set receiving loops.
